drum journals and the transmission gear, Fig. 5 is a detail side view ofthe rear wheel for the upper conveyer chain showing the upper supportingbeams therefor in section. Fig. 6 is a transverse section of a conveyerwheel rim provided with a rubber tire. Fig. 7 is a transverse section ofa conveyer wheel rim having radial retaining pins on the inner flange ofits rim.

This machine will preferably be mounted on wheels, not shown, in orderto readily transport it in mountainous districts. The framework isconstructed with longitudinal lower U-beams 1, longitudinal intermediateU-beams 2, and longitudinal upper U-beams 3, and transverse arched beams4, one at each To all whom. t may concern Be-it known that l, JUANFonsnoii, a citizen of the United States of America, residing at SanLuis Potos, State of San Luis Potosi, Mexico, have invented ycertain newand useful Improvements in Hackling- Machines, of which the following isa specification.

My invention relates to improvements in machines for tearing up theleaves of fibrous plants such as the maguey plant, hitherto refractoryto shredding, and also the lechuguilla and for removing all the bagasseor fleshy parts from the bers at the same time and to which action theleaves are gradually subjected in such a manner that the hackling takesplace endwise and approaches the middle of the leaves and in a secondstage of the operation the same action is effected from the end of theother half of the leaves and clearing beyond the middle of the leaves inorder not to leave any part of the entire length of the leaves withouttreatment.

rlhe object of such gradual treatment is to remove the bagasse or fleshyparts in small portions by the hackling drums and by stripping thefibers from the extremities of the leaves toward the middle of theleaves so that choking or accumulation of the separated bagasse orfieshy parts is avoided and which otherwise, as deposits, adhering tothe fibers, would present a serious obstacle to an advantageous workingon plants with soft and fine fibers.

My machine furthermore provides an effective means for retaining thecleared fibers against the pull of the hackling drums. Y ln order thatthe invention may be more fully understood l will proceed to describe itwith reference to the accompanying drawings in which:

Figure 1 is a top view of my improved hackling machine; the conveyerchains being omitted. Fig. 2 is a side elevation of the same; theconveyer chains being indicated in broken lines. Fig. 3 is a front endview thereof; the gear wheels and conveyer chains being omitted. Fig. 4is an elevation of the double standard for the front end of the A is thefirst hackling drum, of conical shape, located near to one side of theframework, with its smaller end directed toward the feed end of themachine. This first hackling drum is fixed to a driving shaft 5journaled in the single standards 6 and the double standards 6a whichrest upon the lower beams 1. The driving shaft 5 is provided at itsinner end with a worm '7 and at its outer end it carries the gear wheel8, and a driving pulley 9, from which the various parts of the machinereceive movement. Retired or isolated from the first hackling drum A, isa second hackling drum B, also of conical shape, located near to theother side of the framework with its smaller end also directed towardthe feed end of the machine. This second hackling drum B is fixed to adriven shaft 10, journaled in two standards 11, and the double standard6a, all of which rest on the lower beams 1. To the front end of thisdriven shaft 10, is secured the gear wheel 12, which is meshed by thegear wheel 8, en the driving shaft 5, and rotates the second hacklingdrum B in a direction contrary to the movement imparted to the firsthackling drum A.

The conveyance of the leaves is effected transversely in front of thefirst hackling drum A, and the means employed consists of a frontconveyer wheel 13, a lower and larger intermediate conveyer wheel 14,and

a rear conveyer wheel 15. The front conveyer wheel 13 is mounted inshort arms 17 pivoted to the outer ends of the upper beams 3, andyieldingly pressed downward by -leaf or plate springs 18 extendingthereover. The intermediate conveyer wheel 14, of which a cross sectionof its rim is shown in Fig. 7, has a number of radial retaining pins 19on the inner flange of its rim which faces the first hackling drum A,wherebyeven under a great lateral pull the upper conveyer chain 16 andthe lower conveyer chain 20, may be kept wit-hin the channel of the rim.The rear conveyer wheel 15, is mounted on an axial pin 15a supported ina turn on' a sleeve 15c having lugs 15b and l5d respectively secured bybolts 15e to and between the upper beams 3.

Cooperating with the upper conveyer chain 16 is the lower conveyer chain20, running over a lower front conveyer wheel 21, supported on apedestal 22, and also over a small conveyer pulley 23 adjacent to theintermediate conveyer wheel 14 and then below the latter over anotherconveyer wheel 24 secured to a conveyer drum 25 in rear of theintermediate conveyer wheel 14, see Fig. l, and iinally under an.intermediate conveyer idler wheel 26 at the base of the framework.

The carrying of the half treated leaves in front of the second hacklingdrum B is aci, complished by a single conveyer chain 27 traveling over aconveyer wheel 28 and also under a larger conveyer wheel 30 alsoattached to the conveyer drum 25 and then over a conveyer wheel 29,while the larger intermediate conveyer wheel 30 having a rubber tire 31(see Fig. 6) offers a very effective hold on the bers confined betweenthe conveyer chain 27 and the tire 31. The conveyer wheel 29 issupported in a sliding block 32, which plays within a slot 33, of astandard 34, and is forced upward by a spring, not shown, surroundingthe eXtremity of a screw bar 35, provided with a nut 36 for adjustingthe tension.

In Fig. 1 the conveyer wheel 29 is shown as having attached thereto adrum 37 on the top of which a rubber belt 38 is moved by friction; thisrubber belt 38 running over the belt'pulleys 39 and 40, and drawing thecleared fibers from the intermediate conveyer wheel 30, above theconveyer wheel 29 and the drum 37 from where the fibers are discharged.The shaft 4l upon which the conveyer wheel 24, the conveyer drum 25, andthe conveyer wheel 28, are secured has also attached to it at its outerend the worm wheel 42. e

The conveyer drum 25 is provided forthe purpose of supporting thecleared parts of the leaves and prevents such parts from falling betweenthe two parallel running sets of 'face thereof to move in advance of theother,

conveyer chains and also for lifting the cleared parts of the leaveswhich after being cleared are slack, and so that the cleared parts maybe placed on top of the conveyer chain 27 where it turns around theconveyer wheel 28.

Both of the hackling drums are provided with encircling rows of teeth 43arranged with ecreasing spaces between them toward the base of the cone.Y

It will now be understood that in operation the different parts of themachine moved in the direction indicatedby the arrows, the brous leavesmay be inserted between the two conveyer chains 16 and 2O in such amanner that the open ends of the leaves, which result from being cutoffof the plant, will project against the rst due to the semi-circu` lingdrum A, and also in view of the conical shape of the drum, the hacklingcommences at the extreme end of the leaves, and as these advance towardt-he larger periphery of the drum, a longer portion of the leaves willcome within the action of the teeth, in fact almost up to that part ofthe leaves which is embraced by and 20. By the further traveling ofthese conveyer chains the now hackled part of the leaves, which arestill integral with the other part, which is not yet treated, is drawnover the conveyer drum 25, and immediately 'taken hold of by theconveyer chain 27, which,

being" by the coperatie-n of the conveyerk the two conveyer chains 16Vwheel 30, advances the leaves in front of the Y second hackling drum B,and, by operations similar to those of the first hackling drum A,concludes the hackling of the leaves. At this stage the rubber belt 38,which is in fric- Vtional connectionwith the conveyer drum 37,

discharges the bers.

aving thus described my invention the following is what I claim as newtherein and desire to secure by Letters Patent:

l. A hackling machine comprisinga shaft, conical drum mounted on theshaft with its smaller end directed toward the feed end of the machine;the with encircling rows of teeth; therows of teeth being decreased indistance apa-rt from the smaller to the larger Vend of the drum, g theleaves in front of the working face of the drum and means for as tocause the working upwardly.

2. A hackling machine for fibrous plants comprising two parallel shafts,conical drums mounted one on each shaft and one each conical drum beingprovided with encircling" rows of teeth; the rows of teeth on each drumbeing drum being provided decreased n distance apart from the smaller tothe larger end of the drum and means for conveying the leaves in asemi-circular path in front of the working face of eaoh of the drums andmeans for rot-ating the drums so as to cause -the Working faces thereofto move upwardly.

Copies of this patent may be obtained for ve cents each, by addressingthe Commissioner of Patents,

In testimony whereof I have afflxed my signature n presence of t-WoWitnesses.
